Showing up late to work

"The professional thing to do is to arrive on time, ready to do what is expected. It's not like they just sprung this job on you," she says.

Similarly, arriving late to meetings shows that you neither respect your coworkers — who showed up on time, by the way — nor the meeting organizer, Vicky Oliver, author of "301 Smart Answers to Tough Interview Questions," tells Business Insider.

"Keeping people waiting can be construed as inconsiderate, rude, or arrogant," Randall says.

Being negative all the time

Repeatedly responding to suggestions with a pessimistic or contrary attitude can be construed as being uncooperative, Randall says. Phrases like "That won't work," "That sounds too hard," or, "I wouldn't know how to start," should be avoided.

Similarly, complaining too much puts you in a bad light.

"While there may be times when everyone feels the desire to complain about the boss, a coworker, or a task, voicing it will only make you look unprofessional," Randall says. "It's even worse if you complain every day, all day, from the moment you walk into work. Before long, people will go out of their way to avoid you."

"There's nothing as energy-draining as having to deal with a pessimistic coworker," Rosemary Haefner, chief human-resources officer for CareerBuilder, tells Business Insider. "Things do go wrong, but even when they do, focus your energy towards what you've learned from a bad situation."

She points to a recent CareerBuilder survey, which shows that a majority of employers — 62% — say they are less likely to promote employees who have a negative or pessimistic attitude.

Playing '20 Questions' on every new assignment

There may be no stupid questions, Oliver says, but there are certainly annoying questions. These are the kinds of questions that prove you really don't want to do the assignment or illustrate you only want to hear yourself talk.

"When you receive a new assignment, gather your questions, and pose them in an organized way," Oliver suggests. "Never just spout out question after question off the cuff."

"If you're like me, who works well in a semi-messy environment, it can be inhibiting to be clutter-free. But with open cubicles or workspaces, the professional thing to do is to make some compromises," Randall says. "It would be disrespectful and inconsiderate to expect your coworkers to deal with your mess."

According to Haefner, employees who don't clean up after themselves can hurt their chances for a promotion in the eyes of 36% of employers.

Being distracted during meetings

"There is a reason why texting is illegal while driving: It's impossible to concentrate fully on two things simultaneously," Oliver says.

Texting, surfing the web on your laptop, instant messaging, emailing — doing any of these things during a meeting shows everyone else in the meeting, especially your boss, that you're not paying attention.

"They know that while your butt may be planted in the chair, your mind is roaming," Oliver says.

Interrupting

"It's rude to interrupt. When you do, it shows others that you don't have any respect, judgment, or patience," Randall says.

While participation can earn you some brownie points, bad timing can wipe those points away.

Practicing poor hygiene and grooming

At the same time, you want to look like you take your job seriously when you walk into work, and your hygiene and appearance play a role in that.

"Poor hygiene and sloppy clothes scream, 'I don't care!' and are a surefire way to put off those around you," Randall says.

Your boss may wonder whether your attitude about how you present yourself extends to your work, she explains, and you may be passed over for a promotion, overlooked when it's time to meet with a client or represent the company at a conference, and not invited to social gatherings.

Discussing your personal problems

Oliver says there are two issues that arise from openly discussing personal problems like your ongoing divorce at work: "First, you just don't look like you are actively employed when you spend hours a day dishing about your ex. Second, you're discussing a personal problem at the office when you're supposed to be a maestro at solving problems."

"The place for disclosing confidences is outside the office," Oliver says.

Talking about political or partisan issues

Certainly, you spend so much time at work that you may have built up a chummy relationship with your coworkers and bosses, which makes you feel entitled to express your opinions.

But you're walking a fine line when you bring politics into the workplace.

Passionate discussions are to be expected in the workplace, but they should really be focused on work-related issues.

At the end of the day, you're there to do work, and political or partisan arguments can be distracting to both you and your coworkers.

What's more, as an employee expressing yourself at work, it turns out you havefewer protections than you'd think— and if your boss doesn't like what they hear, you could get fired for it.

"Before you pull up your soapbox, you should be aware that in most cases, free speech in the workplace is limited or non-existent when it comes to controversial movements or topics," Randall says.

Nosiness

"There is a line between curiosity and nosiness, which you don't want to cross," Oliver says. Curiosity, she explains, is when you ask who the new hire is. Nosiness, on the other hand, is when you rifle through your boss's files to see how much the woman three cubicles down earns.

Unseemly bathroom chatter

There are two conversations in particular that you should never initiate in a work restroom, Randall says:

The first is a conversation with someone who is using the bathroom.

"Cornering someone in the restroom to hold a conversation, especially when they are in their private stall, is awkward and intrusive," Randall says. "They have the right not to respond while conducting their business." If you must converse, at least wait until you're washing your hands.

And the second is a conversation with someone on the phone.

"You might not care if the person on the other end hears your business, but don't assume that others don't," Randall says. "Besides, I can't think of anyone who finds the sounds of toilets flushing pleasant. It's just plain rude."

Selling stuff

It seems like almost every office has one or two people who sell cookies for their kids. But Randall says that some companies prohibit soliciting at work because it takes up work time and places people in an awkward position. Breaking the rules could be grounds for firing.

Soliciting signatures, volunteers, or donations

"Before you go cubicle to cubicle enlightening your coworkers about your cause, read the company policies and procedures manual. Most companies discourage or forbid promoting personal causes, especially on company time because it's deemed disruptive," Randall says.

Being too noisy

Whether you play music loudly while others are trying to work or have conversations the entire office can hear, then your coworkers likely consider you one of the most annoying distractions on earth.

Being noisy, especially in an open office, has a significant effect on your coworkers' focus and productivity, and the noise could hurt business if it carries into an important phone call.

"Try to show your coworkers that you respect them by keeping the music down, and hopefully they will return the favor," Oliver says.

Making personal calls all day long

Talking or texting with friends or family on company time is unprofessional and could be against company policy, Randall says. What's more, doing it during a break is fine, but these correspondences should be kept out of the workplace, even the lunch room.

"You never know when your boss may walk by for an impromptu chat," she says. "What will they see or hear?"

"If the topic of conversation is of a delicate nature, be sure to keep it private. One overheard juicy tidbit can spread like wildfire," Randall says.

Being overtly cliquey

"Maybe the new guy who smells like French Onion Soup is not your favorite person on staff," Oliver says. "That's no reason to flee him every time he asks you for help on an assignment." Nor should you be spreading gossip about him, Haefner says.

It's best to act friendly toward everyone, Oliver explains: "You will come across as more of a team player and show you have management aptitude."

Spreading out

Don't be the one who edges into other people's personal space, Randall warns.

"You know the ones — they place their coffee mug just so, a comfortable reaching distance, making room for their notebook, elbows, and of course their cell phone and protein bar," she says. "As the person seated next to them, you're left with only enough room for a water bottle."

Swearing

"Using foul words or questionable language is not only a bad habit, but in most places of business, it's still considered unprofessional and can even land you in Human Resources for a little chat," Randall says.

Swearing demonstrates to others that you aren't able to calmly and thoughtfully deal with a situation, and it could make you the last resort in an even more difficult or extreme dilemma, she says.

Haefner says that more than half of employers CareerBuilder surveyed consider vulgar language an indication that an employee is not ready for promotion.

Not only can these habits be distracting to others, but they could also be perceived as boredom.

"Perception is a person's reality," Randall says.

Avoiding work social events

Whether you're shy or you feel like you have better things to do, never attending company-hosted events, declining coworker lunches, and calling in sick on team building days gives the impression that you are antisocial, arrogant, and not a part of the team, Randall says.

"So, next time when you need a favor from your coworkers, don't be surprised if they go MIA," she warns.

Obnoxious email habits

From not including subject lines to sending 'urgent' emails that aren't urgent, poor email form can really rub your coworkers the wrong way.

While mastering the art of good email etiquette doesn't mean sending out beautifully crafted prose each time — that would take forever — if you can avoid these bad habits, you'll be off to a great start.
